To all whom it may concern:

Be it known that we, JULIUS E. STRAUGH and Josnrn C. WEGSTEIN, citizens of the United States, residents of Washburn, in

the county of VVoodford and State of Illispring wheels, the principal object being the provision of a device adapted for automobiles and other vehicles on which a solid tlI'B may be used and which at the same time affords sufliciently yielding'support therefor,

so that all the advantages derived from the use of a pneumatic tire are attained and the disadvantagesobviated.

A further object of our invention is the provision of such a wheel having the rim supported on the hub by meansof two series of flat springs, each series' extending in oppositedirections and each spring being of suflicient length and curvature so that its points of attachment to the hub and rim are diametrically opposite each other. 7

A further object is the improvement in the hub and rim structure of a device of this character whereby the wheel may be quickly and securely assembled.

Further objects include the improvement of details of construction andarrangements of parts whereby a resilient wheel of maximum efliciency is provided.

To the accomplishment of the foregoing and such other objects as may hereinafter appear, our invention consists in the construction, combination and arrangement of parts hereinafter described and then sought to be defined in the appended claims, reference. being had to the accompanying drawings forming a part hereof and which shows merely for the purpose of illustrative disclosure a preferred embodiment of our .invention, it being understood, however, that various changes may be made in practice within the scope of the claims without digressing from our inventive idea.

- Inthe drawings :Figure 1 represents a side elevation of a wheel constructed according to our invention, parts being indicated in dotted lines in the interest of simplicity and convenience. Fig. 2.- is a vertical transverse section broken away in part to facilitate disclosure. Figs. 3, 4c and 5 are detailed views of portions of the hub Specification of Letters Patent.

structure. F ig. 6 is a detail view of the hub end of one of the springs. 1

Referring now to the drawings, it is seen that the wheel comprises a hub structure, a rim andfelly structure and resilient members connecting them, the hub generally benumeral 1, the axle 2, the springs 3, the rim and felly generally 4, and the tire 5.

The-hub 1, as shown particularly in Figs. 2, 3, 4L and 5 comprises three essential parts, the parts 6 and 7 complementing each other to afford a'complete anchorage for both series of spring spokes and the washer or disk 8 being interposed therebetween' to hold the parts in proper spaced relation. The part 6 is formed with the sleeve portion 9 which provides the real hub and fits over the axle being held thereon by means of a nut 10 on the reduced and threaded extremityll. The end of this sleeve 9 is exteriorly threaded as at 12 to receive the dust cap 13. This part 6 ofthe hub structure is also provided with means for holding the inner ends of one series of the spring spokes, this means being provided by the vertical flange or disk portion 14 which is formed with a plurality of sockets or recesses 15, one for each spoke of a series, said sockets or recesses opening out of the inner face of said flange or disk and being widened gradually toward their inner ends, as shown.

The complementary member or part 7 is in the form of a dis: or plate, bored as at 1.6 to fit tightly over the sleeve portion 9 of member 6 and having a plurality of sockets or recesses 17 corresponding in shape and number to the sockets 0r recesses in disk 14; so as to receive the inner ends of the other series of spokes. The disk or washer 8 is interposed between said disk or flange members 14 and 7 and they are held in assembled relation by means of bolts 18 passing through apertures 19 therein.

Each sprin 3 is of simple construction, being prefera ly flat and also of suflicient length so that when in assembled position it extends from its socket 15 or 17 to a point substantially diametrically opposite on the rim, where y the maximum absorption of shock and resiliency is attained. The inner end of each spoke is slightly and gradually widened toward its extremity as shown in Fig. 6 and is also widened in width, so that each spoke is securely anchored in its Patented Dec. 2i, 1915.v
